Kraken is not a wallet. It is an exchange. So I guess you are looking for a good exchange and not wallet. You must understand here and now the difference between wallet and exchange. If it is not clear, just ask, we will help.
As wallet you should use proprietary like the Electrum BEFORE you send money to exchange.
As exchange it will be more or less problematic. Try Bitfinex or GDAX/Coinbase. If they work for you, then fine. If not look further. Esp. at Bitfinex do not hold your coins more than the few hours you need for the conversion.
If you talk to God, you are praying; If God talks to you, you have schizophrenia.
